30-year average mean temperature

Plot updated 1969-12-31 14:00:00

The plot shows how much warmer or colder than
normal each day in the time period was than the temperature in
an average year. Lines that extend above the zero line
indicate that day was warmer than normal, and lines below the
horizontal indicate a day that was colder than normal.

Verticle lines represent the temperature anomaly for that date. The
horizontal orange lines show the average anomaly for the interval shown.
